Dilithium Networks, a supplier of 3G multimedia solutions, has launched a DTG200 gateway product, aimed at resolving the problem of video corruption between the IP network and 3G network.
The DTG2000 incorporates Dilithium Networks’ Video Refresh, a patent pending technology that lessens the duration of video corruption due to air interface, interference and noise, while maintaining the highest possible frame rate.
In the case of video mail message retrieval and streaming applications, video files are typically stored in a compressed format on a server. Corruptions in the bitstream of a video frame not only affect the present picture being processed but can also affect many subsequent video frames for up to 13 seconds. The local detection of the errors by the video gateway simplifies the function of the video-mail server and increases the quality of video.
The DTG2000 can detect video corruption during both the deposit and retrieval of messages.
“The ability to minimize video corruption enables service providers to build next-generation converged voice-video networks and create revenue-generating services, especially for video portal and video mail applications,” Lee Ellison, senior vice president of sales and marketing of Dilithium Networks.
